From my brief history with Xilinx Ultrascale+ PCI cards I recall the golden
image being a sort of known good recovery image.
If we can't tell it should probably be explained better :)

Yes. We do want people to run their entire stack using mainline linux,
not just a part of it, if code is needed to get from recovery image to
full image or similar, then we should support that.
